Sarah Rudd, who once ran analytics for Arsenal, made her name applying the tenets of probability theory to movements on the pitch. Even she admits not everything can be solved with data.

The role of advanced analytics in sports is a contentious subject. To its defenders, data-driven pragmatism is a natural evolutionary step in the way we play and watch games. For detractors, the approach prioritizes results above all else and drains the soul from a pursuit that should be spontaneous and joyful.

As someone who is neither pragmatic nor spontaneous, I don’t qualify for either camp, though I find the very notion of applying this kind of research to soccer fascinating and even admirable. The game is resistant to orderly examination by design. Like preparing a tax return for a housecat, it takes a stupendous amount of ingenuity just to figure out which questions to ask, to say nothing of finding the answers.

While baseball can be a spreadsheet task, soccer matches amount to meandering free-verse written in 90-minute chunks. Luke Bornn is a data scientist who specializes in movement studies. Thanks to his background analyzing complex bodies in motion, he realized he was uniquely suited to explore the nature of such an evasive game. While at Los Alamos National Laboratory, Bornn worked on ways to detect how much damage helicopter blades can sustain before it compromises the chopper’s ability to stay airborne. He has mapped climate data to predict crop yield and studied how herds of massive land mammals move about the fruited plain. The ebb and flow of a soccer match, while mysterious, were not altogether unfamiliar, and he has pioneered ways to quantify some of the game’s amorphous spirit.

I don’t see what’s so hard to understand. Soccer is basically just Brownian motion until a goal is scored.

soccer should probably be modeled by a continuous time recursive bellman equation with a 23x3 dimensional state space (positions of 22 players plus position of the ball)

reply

Can’t wait to see how you’re gonna do the ref! ahahah

reply

How do you map the positions to a single number? Are you planning on using a space-filling curve?

reply

23 x 3, you'll want an x,y,z coordinate for each of them.

Can probably get away with 22x2 + 3 as I'm not sure the z coordinate is necessary for the players if you let them carry around a height and vertical attribute

reply

you probably need the momentum vector of each object too, so 23x6

~lol Looks like it, but actually it's like a 'thousand' variables going on!

reply

So is statistical mechanics but it ultimately amounts to is noise, by and large

reply

Honestly? Stats-wise, it’s pure chaos! ahahah

reply

It's the kind of chaos that make the winner hard to define even with stats

reply

Soccer is less conducive to analytics because it is more free flowing and reactive than other sports. Much fewer set plays and instead reacting to where the ball goes. I would say hockey is the closest in that regard. Hockey has had its challenges with analytics as well.

read up on my math primers @grayruby, soccer is probably best modeled by continuous time bellman equations

reply

Where do I find this?

this was in the context of bitcoin mining, but the idea is to model a system where the state can transition, , according to strategic actions of players within the system, and according to discrete probabilistic events

Football is art, you need to see players like Zidane play it to understand it

I remember this. This might have been soccer's greatest moment.

reply

Not sure if it was the biggest moment ever, but it sure got people talking and made a ton of memes!

Haha

Still part of the art, there is no art without controversy/conflict 😂

Materazzi was begging for it! ahahah

Football is poetry, is off balance by nature
